Hi all,
I'm trying to get some ideas on the best way to do this.
In this particular coding snippet, I was thinking of creating a
dictionary of file objects and file names. These would be optional
files that I could open and parse. At the end, I would easily close off
the files by iterating through the dictionary.
---< CODE FOLLOWS >---
optionalfiles = {fileAreaCode: "areacode.11", fileBuild: "build.11"}
# Try to see if optional file exists, if so, open.
try:
for key, optionalFile in optionalFiles.iteritems():
key = open(optionalFile, "r")
except IOError:
key = False
....
# Close optionally open files
for key, optionalFile in optionalFiles.iteritems():
if optionalFile:
print "Closing: %s" % optionalFile
key.close()
---< END CODE >---
My questions are:
Is this even possible in a dictionary to have a key of a file object?
If so, how do I initialise an empty file object? I mean, something
along the lines of:
fileAreaCode = open("", "r")
If not, any suggestions on achieving openning optional files in a loop?
Otherwise I'm stuck with:
---< BEGIN >---
# Optional input files
try:
fileAreaCode = open("areacode.11", "r")
except:
fileAreaCode = False
try:
fileBuild = open("build.11", "r")
except:
fileBuild = False
....
# Close files
for optionalFile in [fileAreaCode, fileBuild]:
if optionalFile:
print "Closing: %s" % str(optionalFile)
optionalFile.close()
---< END >---
Thanks,
Julian
